GitHub Markdown Print Script

github-markdown-print.js

// Refrence from: https://gist.github.com/beevelop/a0f2c76e79610dca01550c9a93f83876
// Copy following scripts in the developer console of page included markdown content you want to print:

(function () {
	var $ = document.querySelector.bind(document);
	$('#readme').setAttribute('style', 'position:absolute;top:0;left:0;right:0;bottom:0;z-index:100;background-color:white');
	$('#readme>article').setAttribute('style', 'border: none');
	$('body').innerHTML = $('#readme').outerHTML;
	window.print();
})();

Thanks for this! I modified it a little bit to work for GitLab:

(function () {
    var $ = document.querySelector.bind(document);
    $('.md').setAttribute('style', 'position:absolute;top:0;left:0;right:0;bottom:0;z-index:100;background-color:white');
    $('body').innerHTML = $('.md').outerHTML;
    window.print();
})();
